Hi all,
I have a Worcester 24cdi RSF boiler.
Due to re-decorating one of the rooms, I had removed a radiator to repair a hole behind it. When I removed the radiator, I noticed the LSV value was faulty (it leaked when closed), so therefore I drained the system to replace the valve. Replace valve, refilled and bled the system. No problem. Heating and hot water were working fine.
I come to use it this morning and the boiler just clangs, bangs and quickly turns the burner off and expels steam from the top from the type pressure valve thingy. Either in hotwater mode or CH mode.
Any ideas why it would do this and how to fix it?
TIA
Steve
